2024 Plastic Chemical Recycling and Bio-based Plastics Forumwill be held on September 24 in Zhoushan, discussing market opportunities for chemical recycling of plastics and bio-based plastics, waste plastic chemical recycling technologies, projects and advanced equipment, high-performance catalysts and adsorbents assisting in the purification of waste plastic pyrolysis oil, the advantages of bio-refining integrated projects based on corn deep processing, technological and industrial progress in bio-based plastics such as polylactic acid, PHA, PBS, PDO-PTT, HMF-FDCA-PEF, pentamethylenediamine-PA56, bio-based long-chain dicarboxylate esters, and downstream brand manufacturers’ visions for PCR plastics and bio-based plastics.

CO2 Capture Coupled Electrolytic Hydrogen Production Technology (hereinafter referred to as ICCHP technology), is a carbon capture technology independently developed by the State Power Investment Corporation Central Research Institute. This technology route achieves high efficiency and a wide range of carbon dioxide capture using alkaline solutions, coupling electrolytic hydrogen production, desorbing high-purity CO2 at the anode and obtaining O2, while regenerating the alkaline solution and producing H2 at the cathode; during the research process, a linkage platform for the two key links of carbon capture and alkaline solution regeneration was established, achieving rapid regeneration of the alkaline solution and low-cost enrichment of CO2. The average CO2 absorption efficiency is about 50 to 60%, corresponding to a carbon dioxide capture amount of 1.5kg/h; peak hydrogen production exceeds 1000L/h.

The patent layout covers the two core links of carbon dioxide absorption tower and electrolytic hydrogen production, as well as the control system of the linkage platform. This technology is currently promoting the industrialization process through the transformation of results and the establishment of joint ventures with external capital.

Leaders and experts from the State Power Investment Corporation Science and Technology Research Institute will introduce the “CO2 Capture Coupled Electrolytic Hydrogen Production (ICCHP) Technology” at the Asia Chemical 2024 CO2 Capture, Storage, and High-Value Product Forum.

Innovation Highlights:The ICCHP technology scheme, as a new generation of carbon reduction and negative carbon technology, can be summarized in the following innovative highlights: (1) By coupling carbon capture technology with alkaline water hydrogen production, the system cost is reduced; (2) CO2 and H2 can synthesize green chemicals on-site to absorb renewable energy; (3) It resolves the spatial geographic mismatch between CO2 and H2; (4) It has distributed characteristics and flexible application scenarios, applicable to both direct air capture and flue gas carbon capture; (5) The carbon capture cost is low.

Market Prospects:Several business models that ICCHP technology could promote in the future include: (1) Providing overall negative carbon solutions for customers; (2) Manufacturing and selling key core equipment such as electrolyzers; (3) As a negative carbon factory owner, synthesizing methanol, fuel, etc., on-site from captured carbon dioxide and by-product hydrogen for green fuel sales, and selling negative carbon quotas.

Previously, the State Power Investment Corporation Central Research Institute announced the completion of the transfer of 15 core patents and proprietary technologies for its independently developed technology—CO2 Capture Coupled Electrolytic Hydrogen Production (ICCHP) Technology. The transferee of this technology is Shijia Toupai Company, and the Central Research Institute will continue to promote the transformation of 4 non-core patents and proprietary technologies to establish a joint venture.

The 2024 CO2 Capture, Storage, and High-Value Product Forum will be held on September 27 in Hangzhou. The conference will explore industrial waste gas low-energy CO2 capture technology, direct air carbon capture (DAC) technology, carbon dioxide geological storage and CO2-EOR demonstration experience, CO2 electrocatalytic reduction and photocatalytic reduction technology research and pilot testing, CO2 production of methanol, ethanol, methane, SAF, α-olefins, aromatics, gasoline, carbonates, and biodegradable plastics, CO2 artificial synthesis of starch, CO2 bioconversion to high-value products, etc.
